To all whomit may concern:

Be it known that I, JAMES W. THOMPSON, a citizen of the UnitedStates, and a resident of Spokane, in the county of Spokane and State of Washington, have invented new and-useful Improvements in Harvesters, of

which the following is a specification. 7

My invention is an improvement in harvesters, and has for its object toprovide an attachment for use in connection with the reel of a harvester for picking. up fallen grain. and laying it over upon the grain table, wherein the reel consists of series of radial arms, each having reel slats capable of taking a position in alinement with the arm or at right angles thereto, and extending in opposite directions, and having means in connection with the reel for changing the position of the slats to cause them to engage beneath the. fallen grain, pick the same up and laythe grain over upon the grain table, and to afterward release the said grain, and wherein means is provided for moving the reel slats into and out of operative position.

In the drawings:

Figure 1 is a perspective view of a portion of the harvester provided with the improvement,

Fig. 2 is a front view partially in section of one of the arms with thereel slats in inoperative position, i j.

Fig. 3 is a similar view with the slats in inoperative position, a f

Fig. 4 is an end view of the reel with the supporting shaft in section, p

Fig. 5 is a perspect've view of one of'the cams, Y ;j.

Fig. 6'is a side view of the same from the inner side, v e

Fig. 7 is a partial perspectiveview showing the switch mechanism for the controlling rollers, and

Fig. 8 is a view similar. to Fig. 6 showing a modified construction of switch operating mechanism. c

The present embodimentv of the invention is shown in connection with the supporting shaft 1 for the reel of aharvester indicated at 2,'and the shaft is provided at spaced intervals with-sleeves 3'having spaced marginal radially 7 extending flanges, and each sleeve supports a series of arms 4, seven in the present instance, the inner ends of the arms being received between the flanges of the sleeves, and the sleeves are mounted to rotate on the shaft. A pair of reel slats 5 connected to the slats by means of links 8 Y in such manner that when" the bracket is moved on the arm, the slats will be swung. A controlling link 9 is secured to the inner end of each bracket 7 and each link 9 has an outwardly extending lug or journal pin at its inner end upon which is journaled a roller 10. The rollersof the arms of each series'are' controlled by a cam secured to the shaft 1 adjacent to the series, each cam consisting of a disk 11 having a marginal flan e -1218, to be later described.

T e portions 12 and 13 of the flange are concentric, but of unequal radius, 'a'nd'at their adjacent ends the'flange has, passages 14 and 15 for the rollers 10 for permitting the said rollers to pass within the flange or outside of the same. Switch plates or gates 16 and 17 are arranged at the passagesv 14k and 15' respectively, each gate beingsecured to a shaft 18'journaled in the flange 13 at the ends thereof, and each shaft 18 has a crank arm at the outer face of the 'disk'll. These crank armsare connected bya link 19,,and the operating mechanism for the gatesis connectedwith the link. i I V The said mechanism consists of a control ling shaft 20 which is journaled' in, a longitudinally' extending groove in theshaft 1, and ateach cam-111213 the shaft has a radial arm 21, which at its outer end is pivoted to the adjacent link. 19 intermediate the ends thereof. Suitable operating mechanism indicated at 22 is connected With a radial arm at one end of the shaft 20,

and by means of the said operating mechaor entrance passage, and a guide plate 23 is arranged at thesaid passage 15 to constrain the rollers to enter the said passage.

The arrangement is such that when the gates are open, the rollers 10 will move as indicated in Fig. Al, passing out at the passage 1 1 and over the high portion of the cam 13 and through the passage 15 into the interior of the flange, moving the reel slat-s into the position of Fig. 2 whenever they are on the high portion of the cam 13, and moving the slats into the position of Fig. 3 when they are within the flange of the cam.

When the gates are closed, the rollers will run idly around the inner portion of the cam, and the reel slats will beheld in the position of Fig. 3, the roller with the slats in this position acting in the same manner as the usual reel. Means is arranged at the rear of the reel and at the level of the shaft l-for preventing the cut grain frombeing carried upward by the reel slats and over the front of the reel. The said mechanism comprises a guide ea formed of Wire or the like, and supported in fixed position, and bent to form a series of passages for receivingthearm with the slats 5 extended.

It will be evident that any cut grain carried up by the arms will be dislodged by this dislodging device 24. The corresponding arms of all of the series are connected by rods 25, which are spaced outwardly beyond the peripheries of the flanges in or der to not interfere with the rollers10 during their movement, and the ends of these rods have angular portions which are connected to sleeves 26 journaled on the ends o'f the shaft. Sleeve 26 at the inner end of the shaft is provided with a sprocket wheel 27, which is connected by a chain 28 with amoving part of the machine to opcrate the reel. j g V I In operation, the reel being driven, with the gates closed and with the rollers inside the flange 12 13, the reel'slats will be held at all times in the position of Fig. 3, and

the standing grain will be knocked over upon the grain table in the usual manner, When,.fhowever, the grain has fallen forward away from the sickle, it is obvious that with the slats in the position of Fig. 3, or with the ordinary reel, the fallen'grain will be merely pushed closerto the ground making' it more diflicult for the sickle to cut the same. When fallen grain is encountered, thev operator will merely move the shaft 20 to open the gates of, all of the cams. Now, when the rollers reach the passage 14 they will pass'out upon the portion 13' of the cam, and the arrangement of the cams is such that this movement ofv the rollers will take place just as the arms are beginning to move downward at the front of the reel, and the reel slats will be thrown in the position of Fig: so that they can enter between the stalks of the fallen grain. Just before the arms complete their downward movement, and when they are in a position about thirty degrees below the horizontal, the reel slats will begin to move outward beneath the fallen grain, and when the arms reach a position about thirty degrees from the vertical, this movement will be completed, and the fallen stalks will be lifted and laid over upon the grain table in the manner shown in Fig. 4.

It will be noticed from an inspection of Fig. 6, that the gates are more than gates, since they are also switches, constraining the rollers to move out through the passage 14 In Fig. 8 is shown a modified form "of operating'mechanism for the gates. In this construction the link 19, which is connected with the arm 21, passes through the eyes of the crank arms 18, and coil springs 30 are arranged on opposite sides of the eyes between stops adjustable on the link and the arms. With this arrangement the connection between the operating mechanism for the switches, and the switches, is a yielding connection.
